NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2014 Mercedes-Benz GLK250:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2014 Mercedes-Benz GLK250 owners say
Air bags
The contact owns a 2014 Mercedes-Benz GLK250. The contact stated that the front passenger's side air bag warning light failed to function as designed. The vehicle was taken to the dealer where the mechanic informed the contact that the sensor light was permanently disabled. The contact then stated that he was informed of NHTSA Campaign Number: 19V010000 (Air Bags). The manufacturer was notified of the failure and advised the contact to call the NHTSA Hotline. The failure mileage was approximately 75,000.
The front passenger side air bag has been stated to be defective. Mercedes told me in February of 2019 they would advise when replacement available. The Mercedes Benz dealer I use in ft myers florida has replaced the air bag in the same model as mine, built later than mine which I do not think is logical. Mercedes has been advised as has the usdot office of defects investigation (nef-109 ela ref: no. 11338070) who wrote me i02n a letter mailed July 31 2020 to file a formal complaint
